Cornmeal Fried Catfish with Rémoulade Recipe

"Catfish can sometimes have an unappealing “muddy” flavor, so to mellow it out, we use a coating of cornmeal and flour spiced up with cayenne pepper and paprika—it gives the fish crunch as well as extra seasoning. Shallow-fry the catfish for a few minutes per side in a cast-iron pan, hit it with a little salt, and serve it with lemon and a rémoulade for dipping. What to buy: Try to buy farmed catfish, as it gets a “Best Choice” rating from the Monterey Bay Aquarium’s Seafood Watch list. If you don’t have cake flour on hand, all-purpose can be used, though the results won’t be quite as crispy. Special equipment: You’ll need a candy/fat thermometer for this recipe...."
